SILICIUMORGANISCHE VERBINDUNGEN LXXII. SUBSTITUIERTE 1,3-DIOXA-2-SILA-CYCLOPENTANE
Birkofer, Leonhard,Stuhl, Oskar
, p. 21 - 29 (2007/10/02)
Silylation of substituted dioles by means of hexamethyldisilazane leads to 2,2,7,7-tetramethyl-3,6-dioxa-2,7-disilaoctane derivatives.Reactions of these dioles with hexamethylcyclotrisilazane afford substituted 1,3-dioxa-2-silacyclopentanes.
